CHARGING AI PARATUS FOR FLUID-PRESSURE MOTORS.

SPECIFICATION forming part of Letters Patent No. 587,037, dated July 27,1897. Application filed June 20,1896 Serial No. 596,254. (No model.)

To aZZ whom it. may concern-.-

Be it known that I, JOSEPH H. HOADLEY, a citizen of the United States,residing at New York, in the county and State of New York,

5 have invented certain new and useful Improvements in ChargingApparatus for Fluid;

Pressure Motors, of which the following is a specification.

The main object of my'invention is to provide means for injecting acharge of lubricant with a charge of compressed air or other fluid whichis supplied to the pressure-reservoir of compressed-air or other fluidmotors.

The invention is particularly applicable I to motor-vehicles run bycompressed air, in

which application of the invention I prefer to attach the chargingdevice to the vehicle and provide convenient means for placing it incommunication with a stationary source of compressed air.

cook or valve.

0 the inlet-port of the charging-head and adapted to be placed incommunication with the source of supply.

In order that my invention may be fully understood, I will firstdescribe the same with 3 5 reference to the accompanying drawings, and

afterward point out the novelty with more particularity in the annexedclaims.

In said drawings, Figure 1 is a detail transverse sectional view of partof a street-railway car, showing my improved charging device appliedthereto. Fig. 2 is an enlarged detail longitudinal sectional view of thecharging device.

1 is the car-body, supported upon wheels 2, and 3 is a ear-seatextending longitudinally of the body. Beneath the seat 3 is supported acompressed-air or other fluid-pressure reservoir 4, having an inlet-pipe5, to which is coupled the tubular head 6 by means of the coupling 7, agland or packing 8 being interposed between the pipe 5 and head'6.

9 is a spring-pressed check-valve seated in the tubular head 6.

r 10 is the tubular charging-head, provided with stop cock or valve 11extending transversely through it and adapted to close its tubularpassage. A port 1 1 extends directly through the valve 11. v

12 is a handle by which the cook 11 is operated.

13 is an offset extending from one side of the head 10 and having aninlet-passage communicating with the bore of the head.

14 is a flexible charging-pipe coupled at 15 to the offset 13 andadapted to be placed in communication with any stationary supply ofcompressed air or other fluid under pressure.

16 is a yoke having a large thumbrscrew 17 seated in a screw-threadedsocket in its lower end and adapted to engage a depression or seat 18,formed in the lower end of the charging-head 10. The yoke 16 is formedwith an inwardly-bent flange 16 at its upper end, which is cut out oropen on one side. The yoke 16 is adapted to embrace the charginghead 10and enlarge the lower flanged or grooved end 6 of the tubular head 6 forcoupling the charging-head to the inlet-pipe of the storage-reservoir ofthe car. By tightening the screw 17 it will be observed that the head 10will be pushed tightly against the gland or packing 20, interposedbetween the heads 10 and 6.

25 is an oil cup or reservoir-having a tubular extension 26, whichenters the tubular charging-head 10 above the stop-cock 11.

27 is a small cock in the tube 26 for the purpose of retaining a chargeof lubricant in the cup 25.

The operation of the charging device is as follows: I prefer to carrythe charging-heads on the car, having it normally coupled to theinlet-pipe of the storage-reservoir, as shown in the drawings. achargingstation, the flexible pipe 1a is coupled to the maincharging-reservoir and a charge of lubricant is placed in the cup 25.The small cock 27 is then opened, allowing the charge of lubricant toflow into the charginghead above the valve 11. The valve 11 is thenopened, and the charge of compressed When the car stops at air will passthrough the charging-head, past the check-valve 9, into thestorage-reservoir of the car, carrying with it the charge of inbricant,which is intermingled with the compressed air in the reservoir. The cup25 is provided with a screw-cap 28, making it airtight, so that the cook27 can be opened simultaneously with the cock 11 to allow the lubricantto flow into the charging-head while the charge is passing to thereservoir.

My invention is of importance because it enables and facilitates theproper lubrication of a charge of compressed air when it is supplied tothe reservoir, it being very important that the air should be lubricatedto obtain the best results in the motor.

Having thus described my invention, what I claim, and desire to secureby Letters Patcut, is

1. In a compressed-air or other fluid motor, the combination of apressure-reservoir, a charging-head adapted to be coupled to the inletof the reservoir and having a stop-cock or valve, a valvedlubricant-supply passage entering the charging-head above the valve, apipe communicating with the source of supply, and a yoke coupling thecharging-head to the inlet of the reservoir, substantially as set forth.

2. In a compressed-air or other fluid motor, the combination of apressure-reservoir, a charging inlet-pipe, a charging device, a yokeengaging the reservoir inlet-pipe and charging device for coupling themtogether, a stop cock or valve in the charging device, and means forconnecting the charging apparatus to a stationary supply, as set forth.

3. In a compressed-air or other fluid motor, the combination of apressure-rescrv0ir, a charging inletpipe having a flanged or groovedconnecting end, a charging tube or head having a stop-cock or valve, ayoke engaging the lianged or grooved inlet-pipe of the reservoir, ascrew engaging the yoke and charging-head for securing the head to theinlet-pipe, and apipe communicating between a source of supply and thehead.
